Slim Walk Quick Reset Socks Beautiful Leg Compression Room Socks and Compression Spats Set There are pea cushions between the toes and in the arch of the foot, which open the toes and stimulate the arch with every step, improving blood circulation (the arch cushion has a non-slip grip). Furthermore, the high-compression design tightens the calves. I purchased these in the late stages of pregnancy last year. The spats were used 2-3 times, and the socks were used for about a month. I no longer plan to use them, so I would like to pass them on to someone who needs them.
